After Gorilla Biscuits broke up and before he formed Rival Schools, Walter Schreifels led the great New York post-hardcore band Quicksand. Quicksand mastered an emotive but muscular form of seesawing judder — more moshed-out than Fugazi, but rhythmically trickier and more open-hearted than their New York Hardcore peers. They’re also the band who headlined the first-ever Warped Tour, topping a lineup that also included L7 and Sublime, because the passing of time is weird.

Quicksand broke up for the second time in 1999 and hadn’t played any shows back together until last night, when they were surprise guests at the Revelation Records 25th anniversary show, held at the Glass House in Pomona. Below, check out videos of them playing “Omission” and their heavy-as-fuck cover of the Smiths’ “How Soon Is Now?” Thanks to Michael_ for the tip.

No word on whether this was a one-off reunion, but judging by that footage, I hope not.
